Go Get Free iTunes Money at Walmart Right Now

Following in Best Buy's illustrious footsteps, Walmart is currently offering digital $100 iTunes gift cards for $80. Which, for those less mathematically inclined, amounts to $20 of free money to spend on apps, books, movies, or season four of The Wire. The deal appears to be only valid on the Benjamin edition, but you'll burn through that in no time. And the "digital" part means that it's as easy as an email to process.

No word on how long this offer lasts, so get on it, pilgrims. [Walmart via 9to5Mac]
